This report provides numerous Snow Water Equivalent (SWE) statistics at the Natural Resources and Conservation Service (NRCS) SNOTEL station Twelvemile Creek . This is accomplished by generating site statistics through opensource platforms like the NRCS Report Generator API and R (Team, R, 2020). The idea is to give a brief summary of the station (summary stats) and then the user can look through other tabs (SWE graph, time series, SWE duration curve, frequency) for deeper analysis.

From the NRCS website, “Snow Water Equivalent, or SWE, is a commonly used measurement used by hydrologists and water managers to gage the amount of liquid water contained within the snowpack. In other words, it is the amount of water that will be released from the snowpack when it melts.” (find more info here)
